Nice German wender; thank you for posting it here. Much appreciated! Looks like a 1700s gun that was flintlock once upon a time. This appears to be the case since it has perc. patent breechs on the barrels, and the screw holes show up on the left side photo of the lock, (they are present also on the right side but are less discernible).
The boss, along side the barrels, for the frizzen spring, shows filled in screw holes, (two, at least). Piece was converted to caplock in Europe, most likely, given the patent breechs and the distinctive percussion hammer, and drums.
The carving is fine and seems to have been executed more carefully than on other such guns I have seen. The interlocked 'C' motifs at the cheekrest have been repeated many times up in the Upper Susq' school and elsewhere, but somewhat less in other gun building areas.
It's a great piece, and deserves to have some work done to conserve/restore it.
Thanks again.
Dick
